Germline-focused analysis of tumour-detected variants in 49,264 cancer patients: ESMO Precision Medicine Working Group recommendations.

Strategic germline-focused analysis can prioritise a subset of tumour-detected variants for which germline follow-up will produce the highest yield of most actionable true germline variants. We present updated recommendations around germline follow-up of tumour-only sequencing including (i) revision to 5% for the minimum per-gene GCR, (ii) inclusion of actionable intermediate penetrance genes ATM and CHEK2 (iii) definition of a set of seven 'most-actionable' cancer susceptibility genes (BRCA1, BRCA2, PALB2, MLH1, MSH2, MSH6, RET) in which germline follow-up is recommended regardless of tumour type.

Adenine base editor-mediated correction of the common and severe IVS1-110 (G>A) ß-thalassemia mutation.

In HSPC-derived erythroid populations, this strategy was able to restore ß-globin production and correct inefficient erythropoiesis typically observed in ß-thalassemia both in vitro and in vivo. In conclusion, this proof-of-concept study paves the way for the development of a safe and effective autologous gene therapy approach for ß-thalassemia.

Biology and therapeutic targeting of molecular mechanisms in MPN.

However, better understanding of MPN biology has led to the development of rationally designed therapies, with the goal of not only addressing disease complications, but also potentially modifying disease course. We review the most recent data elucidating mechanisms of disease pathogenesis, and highlight emerging therapies that target MPN on several biologic levels, including JAK2-mutant MPN stem cells, JAK and non-JAK signaling pathways, mutant calreticulin and the inflammatory bone marrow microenvironment.

Erythroid/megakaryocytic differentiation confers BCL-XL dependency and venetoclax resistance in acute myeloid leukemia.

Combining BCL-XL inhibitor with the JAK inhibitor ruxolitinib showed synergistic and durable responses in cell lines. Our results suggest targeting BCL-XL as a potential therapy option in erythroid/megakaryoblastic leukemias and highlight an AML subgroup with potentially reduced sensitivity to venetoclax-based treatments.

Characteristics of circulating KSHV-infected viroblasts during active KSHV+ multicentric Castleman disease.

We also identified several putative mechanisms of immune escape used by KSHV, as KIV displayed an overall decrease of co-stimulatory molecules with a remarkable lack of CD40 expression and are IL-10 producing cells. The identification of this specific and easily accessible KSHV+ circulating population brings new elements in the understanding of KSHV-MCD but also raises new questions that need to be clarified.

Diminished Humoral and Cellular Responses to SARS-CoV-2 Vaccines in Patients with Chronic Lymphocytic Leukemia.

In the booster vaccination cohort, positive correlations were seen between serologic response and CD4 T-cell responses for both variants (P = 0.58 Wuhan, P = 0.57 Omicron) and to a lesser degree for CD8 T-cell responses (P = 0.33 Wuhan, P = 0.22 Omicron). While no deaths from COVID-19 were reported after booster vaccinations, patients should use caution as newer variants emerge and escape vaccine-induced immunity.

Dual targeting of aberrant DNA and histone methylation synergistically suppresses tumor cell growth in ATL.

DUSP5 was downregulated by DNA methylation and H3K27me3 accumulation in the promoter region in HTLV-1-infected cells from ATL patients during ATL leukemogenesis. The present results demonstrate that dual targeting of aberrant DNA and histone methylation synergistically suppresses tumor cell growth by restoring DUSP5, and the dual targeting of aberrant DNA and histone methylation is a feasible therapeutic approach for ATL.

Engineering amino acid uptake or catabolism promotes CAR-T cell adaption to the tumour environment.

In turn we engineer and phenotype a further generation of CAR-T cells which express functional Arginase I/Arginase II enzymes, and have enhanced CAR-T cell proliferation and anti-tumour activity. Thus CAR-T cells can be adapted to the amino acid metabolic microenvironment of cancer, a hitherto recognised but unaddressed barrier to successful CAR-T therapy.

Enriching single-arm clinical trials with external controls: possibilities and pitfalls.

The validity of the treatment effect derived from indirect comparisons heavily depends on careful methodological considerations included in the proposed 3-step procedure. Because the level of evidence of a well-conducted RCT cannot be guaranteed, the evaluation is more important than in standard settings.

IL3-zetakine combined with a CD33 costimulatory receptor as a Dual CAR approach for safer and selective targeting of AML.

Cytokine-Induced Killer (CIK) cells, co-expressing a first-generation low affinity anti-CD123 IL3-zetakine and an anti-CD33 as costimulatory receptor (CCR) without activation signaling domains, demonstrated a powerful antitumor efficacy against AML targets without any relevant toxicity on HSPCs and endothelial cells. The proposed optimized Dual CAR CIK strategy could offer the opportunity to unleash the potential of specifically target CD123+/CD33+ leukemic cells while minimizing toxicity against healthy cells.

Missense VKOR mutants exhibit severe warfarin resistance but lack VKCFD via shifting to an aberrantly reduced state.

Increased activity also compensates for the weakened substrate binding caused by these mutations, thereby maintaining normal VKOR function. The uninhibitable nature of severe resistance mutations suggests that patients showing such signs should be genotyped and treated by alternative anticoagulation strategies.

Novel risk assessment for the intensity of conditioning regimen in elderly patients.

In contrast, we found no significant differences in NRM between MAC and RIC in patients with a low RICE score (training cohort: HR, 0.99, 95%CI, 0.85-1.15, P = 0.860; validation cohort: HR, 0.81, 95%CI, 0.66-1.01, P = 0.061). In summary, a new and simple scoring system, the RICE score, appears to be useful for personalizing the conditioning intensity and might improve transplant outcomes in elderly patients.

Outcomes following posttransplant viral-specific T-cell therapy in patients with sickle cell disease.

No immediate infusion-related toxicities occurred, and severe de novo acute GVHD occurred in only 2 (15.4%) patients. Given the good safety profile, high-rate of clinical responses and sustained remissions when administered with standard anti-viral treatments, the routine use of VSTs post-HSCT as prophylaxis or treatment may improve the overall safety of transplant for patients with SCD.

A phase 2, prospective, randomized, open-label study of defibrotide added to standard-of-care prophylaxis for the prevention of acute graft-versus-host disease after allogeneic hematopoietic cell transplantation.

Overall survival rates at Day 180 post-transplant were similar between arms, as were the rates of serious treatment-emergent adverse events (defibrotide: 42%, SOC: 44%). While the observed differences in endpoints between the two arms were not substantial, these results suggest defibrotide prophylaxis may add a benefit to currently available SOC to prevent aGvHD following allo-HCT without adding significant toxicities.

Overexpression of the key metabolic protein CPT1A defines mantle cell lymphoma patients with poor response to standard high dose chemotherapy independent of MIPI and complement established high-risk factors.

In addition to deregulated proliferation, we show that thermogenesis, fatty acid degradation and oxidative phosphorylation are altered in patients with poor survival, and that high expression of carnitine palmitoyltransferase 1A (CPT1A), an enzyme involved in fatty acid degradation, can specifically identify high-risk patients independent of the established high-risk factors. We suggest that complementary investigations of metabolism may increase the accuracy of patient stratification and that immunohistochemistry-based assessment of CPT1A can contribute to defining high-risk MCL.

A key role of the WEE1-CDK1 axis in mediating TKI-therapy resistance in FLT3-ITD positive acute myeloid leukemia patients.

Remarkably, pharmacological inhibition of the WEE1 kinase synergizes and strengthens the pro-apoptotic effect of TKIs therapy in cell lines and patient-derived primary blasts. Finally, we propose a new molecular mechanism of TKIs resistance in AML and suggest the combination of WEE1 inhibitor and TKI as a therapeutic option to improve patients clinical outcome.

A pro B cell population forms the apex of the leukemic hierarchy in Hoxa9/Meis1-dependent AML.

Lentiviral overexpression of Sox4 and Bach2 induced dedifferentiation of H9M cells towards a lineage-negative state in vitro as the first step of lineage conversion. This work suggests that the potency to initiate a partial B lymphoid primed transcriptional program as present in infant AML correlates with aggressive disease and governs the H9M LSC hierarchy.

Drug-Drug Interaction between Antiplatelet Therapy and Lipid-Lowering Agents (Statins and PCSK9 Inhibitors).

PCSK9 antibodies target a serine protease (PCSK9), which promotes the degradation of the LDL-C receptor impacting on LDL-C plasma levels and (ox)LDL-C-receptor-mediated signaling in platelets similar to but more potent than statins. These functionally synergistic actions are the basis for numerous interactions between antiplatelet and these lipid-lowering drugs, which may, in summary, reduce the incidence of atherothrombotic vascular events.

A novel tRNA-derived fragment tRF-3022b modulates cell apoptosis and M2 macrophage polarization via binding to cytokines in colorectal cancer.

Mechanistically, we found that tRF-3022b binds to galectin 1 (LGALS1) and macrophage migration inhibitory factor (MIF) in CRC cells and reduces polarization by regulating MIF in M2 macrophages. In conclusion, our study revealed the expression pattern of tRFs in both tissue and plasma exosomes and identified a novel tRF, tRF-3022b, which may affect CRC tumor growth and M2 macrophage polarization by binding to LGALS1 and MIF.
